pictures and music didnt transfer to my replacement devourSupport

I have been having issues with this phone since I first got it and this is the fourth time its been replaced. Every other time I have been able to transfer all my pictures and music to the new phone except this one. When I put my sd card into my new phone only 47 pictures and 6 songs showed up, I have over 700 pictures and around 200 songs. When I put my sd card back into my old devour all my media has shown up and I just don't know what's going on. Can somebody tell me what's wrong and how to fix it? Thanks!

P.s. it had to be replaced bc of a loose charger port and buttons not working, it had nothing to do with the media or sd card.
